I think it's a reasonable take after 15 years of seeing CSS/HTML/JS being abused for everything and more (when all you have is a hammer…), with the result being that many simple static pages are nowadays monstrous JS apps. My conviction is that, had those technologies stayed simple and focused on delivering the "Document" use-case, turning everything into an app would be a much bigger bridge to cross.
That's essentially where the web was at before the HTML5 days: you could already go as fancy as you wanted, at the cost of pushing your users into a java/flash applet (and through longer loading times, high CPU/Memory requirements, …), and that clearly wasn't the norm.
